What does hematologist mean?
A hematologist is a medical practitioner who specializes in hematology, the branch of medicine concerned with blood, blood-forming tissues, and blood disorders. The work may involve examining blood counts, interpreting laboratory results, diagnosing conditions such as anemia, leukemia, clotting disorders, and immune-related blood diseases, and recommending or supervising treatment. Hematologists may work in hospitals, clinics, laboratories, and research settings, and they may specialize further in areas such as pediatric hematology, hematologic oncology, or transfusion medicine. In everyday conversation, the term is sometimes shortened to “blood doctor,” but that expression is informal and less precise. Hematologist is the usual American spelling; British English generally uses haematologist. The word is useful because it precisely identifies the medical professional responsible for one of the body's most informative diagnostic materials: blood.

Where does hematologist come from?
Hematologist is formed from hematology, which combines the Greek haima, meaning “blood,” with -logia, meaning “study of.” The suffix -ist turns the field name into a designation for a specialist, so hematologist literally means “one who studies blood.” The spelling hematologist reflects the usual American convention, while haematologist preserves the British variant spelling.
How hematologist is actually used
This is a formal clinical term. “Hematologist” is the usual American spelling, while “haematologist” is standard in British English. The term most often refers to a physician, although it can also be used more broadly for a specialist in blood science.
